Referring to the drawing in which simi- Y lar numerals indicate identical parts- Figure 1 is a view in part of the bundleV forming and binding end of a corn harvester embodying my invention; and,

Figure 2 is an enlarged detail, in perspective, of my improvement.

In the hard work of harvesting corn, damage to the parts mounted on the trip shaft of the binder mechanism occasionally results and to make repairs it is necessary to remove the shaft, and the parts mounted on it. Heretofore it has been necessary to loosen the various parts on the trip shaft so that the latter can be withdrawn therefrom vertically, the upper bearing in which the trip shaft is journaled, and to which my'improvement relates, being solid as commonly constructed, and the packer links and trip arms being sleeved upon the trip shaft and held rigidly thereon by rivets or keys which would have to be removed before the trip shaft could be dismounted from the machine. By the use of my invention, however, the trip shaft can be readily removed from the machine without separating from the shaft the various parts mounted upon it as clearly set forth hereinafter. f

Illustrating suflicient of a binder mechanism, of which my invention forms a part, 1V

is the binder frame, of the usual type in the section 2 of which is journaled the needle shaft 3, and in the section 4 is journal-ed the knotter shaft 5. In the section 6 of the journaled? the shaft A7. The crank shaftl8 is l' thepower shaft and Von it are mounted the Y packersQ; The crank'shaft'S is supported in a bearing l0 on the frame 1 and inbearings 11 and 12on parts of the harvester fra-m-e structural VThe shafts -mentioned are parts heretoforedescribed are common in the art, are well known' commerciallyand areV only Vcited to clearly locate myA invention;`

. "lhe'lowerv end of the trip shaft 13is supported in a bearing 14 on thelower part of I the frame 1 and in a'bearing l5 on the upper part of the section 2 of said frame; the trip shaftjcarries the Vusual trip arms 16 andre.-

tarding arms 1,7 ^`and operates to trip theV bindingv and discharging `mechanism- The trip arms 16 are mounted on-sleeves 18,

through which the trip shaft extends,` and are secured rigidly to the shaftby rivets or bolts. The packer :links 19V have Asimilar sleeves120 keyed or otherwise secured to the n trip shaft 13,'lthe links l19 beingattached to the packers in thev ordinary mannerY by suitable pins 21. Thetrip shaft has the usual spring controlled rod -cojnnection-22l withfthe tying-devi ce, one end of the '.rod being formed to engage with `an arm 23. integral Awith a sleeve 24 riveted on the lower part of the tripl shaft.V 1

My inventiom however, concerns the bear- `ing 15 which consists of a projection *25, on

the section 2 of theibinder frame 1,V which is provided withr an open slot 26, to receive the` trip shaft,and tolhold the trip shaft` securely'ftherein isa member v27 mounted to slide on theshaft 13'so as to readily ooa'ct with the projection 25 to hold the' shaft in place; the'member Q/ Tbeingprovided with a lug 28 which. fits snuglyin the slot 26, and

It is easily understood that to replace the trip shaft and againmount thereon y the trip arms 16, packer links 19 and the arm 24 requires `considerablepatiente-labor and V'considerable time, but withy the use of 'WLBUR J.
